  • Patent number: 11624900
    Abstract: A system for quantitative differential phase contrast microscopy with isotropic transfer function utilizes a modulation mechanism to create a detection light field having a radial or other axial orientation of optical intensity gradient or other distribution. A condenser generates an off-axis light field to project onto an object under examination, thereby generating an object light field, which is then guided to an image capturing device through an objective lens for capturing images. A differential phase contrast algorithm is applied to the images for obtaining a phase, thereby a depth information corresponding to the phase can be obtained to reconstruct the surface profile of the object.

  • Publication number: 20230083519
    Abstract: A method employs an unmanned aerial vehicle to carry an electromagnetic field measurement system to overcome environmental obstacles in measuring environmental electromagnetic field. The electromagnetic field measurement system senses the electromagnetic field of a spatial position in the environment to generate a sensing signal, then processes the sensing signal to remove the high-frequency electromagnetic interference generated by the operation of the unmanned aerial vehicle itself from the sensing signal, and converts the processed sensing signal into a digital signal. The digital signal is processed to extract at least one wave according to a fundamental frequency and a harmonic order, thereby removing the low-frequency electromagnetic interference from the digital signal. The extracted wave is employed in calculating an environmental electromagnetic field value of the spatial location.
